D'Addario H315 4/4M C Violin Strings

Helicore Low C String for 4/4 Violin — Warm, Responsive, Built to Last

The D'Addario Helicore Violin Single Low C String is a replacement string for full-size 4/4 violins, scaled to a 328 mm playing length. It uses D'Addario's stranded steel core technology — steel wires braided together into a flexible cable that blends strength with quick bow response. The C string is tungsten/silver wound, giving the lowest voice on the instrument a warm, clear, focused tone that holds pitch through extended practice and performance. Medium tension keeps the feel balanced under the fingers, and the ball-end fitting drops into any standard fine tuner tailpiece. Designed, engineered, and manufactured in D'Addario's New York production facility, this single string is the right choice for players who need to replace a worn C or expand a four-string violin into a five-string setup.

Who This String Is For

Advancing students, intermediate players, and professionals who need a reliable replacement C string for a full-size violin will find this string a practical choice. It works equally well for traditional classical repertoire, folk and old-time fiddle styles, and electric five-string violin setups where cross-tuning is part of the playing routine. Players who switch between musical styles will appreciate how the stranded steel core delivers a clear, warm tone with the bow response needed for fast passages and sustained notes alike. The medium tension suits the majority of instruments and playing approaches, making it a straightforward upgrade or replacement for any 4/4 violin. Whether completing a five-string conversion, replacing a worn C, or seeking the tonal consistency of the Helicore line across all four strings, this single string delivers the same pitch stability and longevity that players report across the full range.
